Assessed honeyed drink — certainly can be swallowed (8)
I believe the answer is:
measured
'assessed' is the definition.
('measure' can be a synonym of 'assess')
'honeyed drink certainly can be swallowed' is the wordplay.
I cannot quite see how this works, but
'certainly' could be 'sure' (synonyms) and 'sure' is located in the answer.
'drink' could be 'mead' (mead is a kind of drink) and 'mead' is found within the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for measured that I've seen before include "Dare Muse be regular in movement" , "Determine dimensions" , "Calculated amount" , "Made sure (anag.)" , "Rhythmical, regular in movement" .)
